Title: A method of extracting crude mineral wax from coal
IPC: C10G73/00
Filed: 1961-01-13
Abstract: Crude mineral wax is extracted from coal by a process in which the coal is crushed to a grain size less than 2mm., and preferably less than 0,06mm., exposed for not more than 5 seconds at 500-1200 DEG C, to flue gases having an oxygen content not more than 4%, and thereafter extracting the coal grains with an organic solvent such as benzene.

Abstract: 701,373. Conveyers. FREEMAN (ENGINEERS), Ltd., A., and FREEMAN, A. Jan. 8, 1951 [Jan. 19, 1950], No. 1449/50. Classes 78 (1) and 104 (2) [Also in Group XXV] A conveyer chain for moving goods or articles is made up of links each comprising a body formed by a rod of elongated loop form embracing and secured to a spindle which extends transversely of the body and on which is loosely mounted, at each side of the body, a guide wheel or roller for the chain, associated ends of adjacent links being articulated together to allow relative up-and-down and relative lateral movement between these links. Figs. 1, 2 show the application to a chain for transporting shoe lasts 16 between stations to be dealt with by different operators. The chain which may be endless, comprises links 3 each provided with pairs of guiding rollers 4 on pins 6 engaging the internal surfaces of a guide-way 1, adjacent links being at right angles to one another. Each pin 6 is inserted into its link 3 through a gap 7 in one limb of the link and after being slid along to the required position, the limbs of the link are compressed a little to hold the pin firmly. The rollers are held on the pins 6 by spring clips. The guideway 1 is built-up of four angle irons 10 connected together by brackets 11 some of which are used for suspending the conveyer from supports 12. These angle irons are spaced to form gaps 13, one of which is used for the passage of carriers 14 which are welded to the appropriate links and support hooks 15 for the lasts 16. If a last is not removed on arriving at a particular station, switch means may be operated to effect stoppage of the chain. In a modification Fig. 4 (not shown). the lasts are supported on pegs upstanding vertically from the chain. Alternatively the pins 6 may be extended so as to form supports. In another modification projections on the chain serve to propel carriages along a rail beneath or alongside the guideway 1.

Abstract: 1,152,562. A process for producing methanol. METALLGESELLSCHAFT A.G. 10 Jan., 1968 [11 Jan., 1967], No. 1486/68. Heading C2C, Methanol is produced from synthesis gas which contains carbon monoxide, hydrogen and up to 10% by volume of CO 2 , with the aid of a methanol synthesis catalyst, under superatmospheric pressure and at an elevated temperature, and wherein dimethyl ether formed as a byproduct in the process is distilled from the liquid reaction product and is recirculated into the process. Water may be added to the dimethyl ether-containing gas which is recirculated to the process, especially when the synthesis gas has a carbon dioxide content less than 0À2% by volume. In this way a higher conversion of carbon monoxide and hydrogen to methanol and a reduction of synthesis gas losses due to the formation of dimethyl ether are obtained.

Abstract: 793,791. Cold-cathode-tubes. GENERAL ELECTRIC CO., Ltd. Dec. 8, 1955 [Jan. 19, 1955], No. 1643/55. Class 39(1). In an electric discharge device of the type having within a sealed-envelope provided with an ionizable gas or vapour filling at least two electrodes and a quantity of radio-active material for facilitating the starting of a discharge between the eletrodes on the application of a discharge-initiating potential difference between them, the radio-active material is contained within a sealed metal enclosure mounted within the envelope of the device. The cold-cathodetrigger tube shown is similar to that described in Specification 726,928 and comprises a cathode 1 in the form of a rectangular nickel sheet coated on one surface with electron emissive material such as barium-strontium-calcium oxide, a rod anode 4 and trigger electrodes 5 and 6. A pellet 9, consisting of gold foil impregnated with radium sulphate sandwiched between two nickel foils which are cold-welded together at the edges, is spot welded to the trigger-electrode 6 or alternatively to the anode 4 or to one of the cathode support rods 2. The rod 5 may act as the only trigger electrode, in which case the rod 6 serves merely as a support for the pellet 9. An alternative form of pellet is obtained by cutting a small length of nickel tube containing a core of radio-active material so that the cut ends are closed by cold welding. The gas filling consists of neon plus 20 per cent argon at a total pressure of 40 mm. of mercury. Specifications 733,213, 737,386 and 748,906 also are referred to.

Title: Improvements in methods of and apparatus for generating toothed gears
IPC: B23F5/16
Filed: 1938-01-18
Abstract: 502,055. Gear-cutting. STUBBS, E., and FELLOWS GEAR SHAPER CO. Jan. 18, 1938, No. 1691. [Class 83 (iii)] In a method of and apparatus for generating toothed gears (or segments), the blank B is cut by a number of equi-spaced reciprocating segmental pinion cutters arranged therearound, the blank and the cutters having a slow rotary generating movement which is continued until the teeth ,are completely cut, Fig. 2. The cutters are positioned at such radial distance from the blank that no depth feed is required and each cutter may have either one or, as shown, two series of teeth t' and t<2> the former taking roughing cuts and the latter finishing cuts. For cutting gear segments the cutters may be arranged around part only of the work circumference. Since each cutter has four finishing teeth any number up to 24 teeth may be cut in the blank but in the form shown 21 teeth are being cut, the cutter spindles being so timed that each cutter meshes correctly with the blank. The generating motion may be obtained either by rotating the blank and cutters simultaneously or by giving the cutters a rolling planetary movement round the stationary blank. Where two sets of cutter teeth are used.the finishing teeth of one cutter enlarge and finish the spaces generated by the roughing teeth of the preceding cutter. In a machine embodiment, Fig. 3, the blank a is mounted on a fixed arbor 10 and the cutter spindles are mounted in a cylindrical carrier 12 which is rotated to give the orbital movement by worm gearing 16. At the same time the carrier and cutter spindles are reciprocated by a segment 14 engaging the circular rack 15. Generating rotation of the cutter spindles on their axes is imparted by gears 20 which roll on a stationary gear 19. For generating helical gears the cutters are also helical and the gears 19, 20 have the same helical angle as the cutter teeth. To relieve the cutters on their return strokes the conical bearing portions 21 of the cutter spindles are journaled in a movable head 23, pressed forward by springs 24 and connected with a rod 25 moving axially with the carrier. At the end of the cutting stroke the rod 25 has additional movement imparted by gearing 27 so that the spindle bearings 21 are freed and the spindles may be moved laterally by springs 28 to withdraw the cutters. At the end of the return strokes the gear 27 is again operated to tighten the spindle bearings 21.

Separating gaseous mixtures by liquefaction. - In the separation by partial condensation of coke oven or other gas mixtures, a gas of low boiling-point such as nitrogen, under pressure, is cooled by the main body of constituents condensing out. and subsequently expanded and liquefied serving as a bath for the last condensation stage. Coke oven gas supplied by a pipe 1, Fig. 1, and compressed nitrogen supplied by a pipe 11 pass through a heat exchanger 10. Methane begins to separate out in the coil 3 and the nitrogen is liquefied in the coil 12. The remainder of the methane is liquefied in the coil 5 by the nitrogen. which is expanded through valve 13. The methane is expanded through valve 8 into the vessel 4 surrounding the coils 3, 12 where it is completely revaporized. In the modification shown in Fig. 2, part of the nitrogen is supplied through a pipe 22 cooled by a return flow of expanded gas. The methane condensed and deposited in the vessel 7 cools the nitrogen in the exchanger 15 before returning to the vessel 4. The. liquid nitrogen is used to wash the residual permanent gases in a vessel 16 and the impure liquid deposited in this vessel is expanded into the vessel 6 to complete. the liquefaction of the methane.
